The iPhone XR, XS, and XS Max will not get iOS 19.

Juli Clover from MacRumors:

iOS 19 will not be available on the iPhone XR, ‌iPhone‌ XS, or the ‌iPhone‌ XS Max, according a private account on social media site X that has accurately provided information on device compatibility in the past.

The ‌iPhone‌ XR, ‌iPhone‌ XS, and ‌iPhone‌ XS Max all have an A12 Bionic chip, so it looks like ‌iOS 19‌ will discontinue support for that chip. All other iPhones that run iOS 18 are expected to support ‌iOS 19‌.

It will be the end of an era, as the XS and XS Max were the last iPhones to have 3D Touch support, a feature that was always hidden under the radar, but was a stealth pro feature for those who knew about it.

It was so stealth that the iPhone XR was the first iPhone to remove 3D Touch, but still became the best selling phone in 2019.
